Understanding Ultra3000
I/O Specifications
A description of the Ultra3000 digital I/O power requirements and I/O
signal specifications is provided on the following pages. Also included
are I/O circuitry examples.
Digital I/O Power Supply
All Ultra3000 drives require an isolated external 12-24V power supply
for proper operation of the digital I/O.
The following table provides a description of the digital I/O power
supply (CN1-29 and -30).
Auxiliary 5V Logic Supply
The Ultra3000 drives (2098-DSD-005, -010, and -020) require an
external +5V power supply in applications in which it is necessary to
maintain logic power when the AC line voltage is removed. The +24V
I/O supply (IOPWR) allows use of the drive-mounted breakout boards
with 24V to 5V dc converter (2090-U3CBB-DM12 and -DM44). The
following table provides a description of the +24V (IOPWR) power
supply requirements when used to maintain logic power.
IMPORTANT
Do not tie the 24V digital I/O common (CN1-27 and
-28) to the auxiliary encoder +5V common (CN1-2).
Parameter Description Minimum Maximum
I/O Power Supply
Voltage Voltage range of the external power supply for
proper operation of the digital I/O.
10.8V 26.4V
I/O Power Supply
Current
Current draw from the external power supply for
the digital I/O, not including the relay output
usage.
— 300 mA
Parameter Description Minimum Maximum
Input Voltage
Range
Input voltage range of the external power
supply for drive-mounted breakout boards with
24V to 5V converter.
18V 30V
Input Current
Input current draw from the external power
supply for the drive-mounted breakout boards
with 24V to 5V converter.

IMPORTANT
A single 24V power supply can be used to power the
digital I/O and supply 24V to the drive-mounted
breakout boards (2090-U3CBB-DMxx) provided the
cumulative minimum current requirements are met.
